2 DESCRIPTION
2.1
Drive
The machine has 4-wheel drive. The power from
the engine to the drive wheels is transferred hydraulically. The engine drives an oil pump, which
pumps oil through the rear and front axle drives.
The front axle and rear axle are connected in series, which means that the front wheels and rear
wheels are forced to rotate at the same speed.
To make turning easier, both axles are equipped
with differential.
Front-mounted implements are powered via drive
belts.
2.2
Steering
The machine is articulated. This means that the
chassis is divided into a front and a rear section,
which can be turned in relation to each other.
The articulated steering means that the machine
can turn around trees and other obstacles with an
extremely small turning radius.
2.3
Safety system
The machine is equipped with an electrical safety
system. The safety system interrupts certain activities that can entail a danger of incorrect manoeuvres. For example, the engine cannot be started if
the clutch-parking brake pedal is depressed.
The operation of the safety system must
always be checked every time before
use.

4 STARTING AND OPERATION
The machine may not be operated unless the engine casing is closed and
locked. Risk of burns and crushing injuries.
4.1
4.2 Checking the engine oil level
On delivery, the crankcase is filled with SAE 10W40 oil.
Check the oil level every time before using to
ensure it is correct. The machine should be
standing on level ground.
Wipe around the dipstick. Unscrew and
pull it up. Wipe the dipstick.
Pro 16, Pro 20, Pro25:
Push the dipstick down completely and screw into
place.
Unscrew and pull the dipstick up again. Read off
the oil level.
Pro Svan:
Push the dipstick down completely without screwing it into place. Pull it up again and read off the oil
level.
Top up with oil to the “FULL” mark if the oil level
is below this mark. See fig. 9-11.
The oil level must never exceed the “FULL” mark.
This results in the engine overheating. If the oil
level exceeds the “FULL” mark, the oil must be
drained until the correct level is achieved.
Safety checks
Check that the results of the safety checks below
are achieved when testing the machine in question.
The safety checks must always be carried out every time before use.
If any of the results below is not
achieved, the machine must not be
used! Take the machine to a service
workshop for repair.
Filling with petrol
Always use lead-free petrol. You must never use 2stroke petrol mixed with oil.
The tank holds 14 litres. The level can easily be
read through the transparent tank.
NOTE! Ordinary lead-free petrol is a perishable
and must not be stored for more than 30 days.
Environmental petrol can be used, i.e. alkylate
petrol. This type of petrol has a composition that is
less harmful for people and nature.
Petrol is highly inflammable. Always
store fuel in containers that are made
especially for this purpose.
Only fill or top up with petrol outdoors,
and never smoke when filling or topping up. Fill up with fuel before starting
the engine. Never remove the filler cap
or fill with petrol while the engine is
running or still warm.
Never completely fill the petrol tank. Leave an
empty space (= at least the entire filler tube plus 1
- 2 cm at the top of the tank) to allow the petrol to
expand when it warms up without overflowing.

When the machine is in operation, full throttle
should always be used.
4.5
Power assisted steering
(Pro20, Pro25, Pro Svan)
Power assisted steering means that power from the
machine’s hydraulic system is supplied to the
steering wheel movements. This makes the machine very easy to steer when the engine is operating at working revs (full throttle).
The servo effect is reduced as the engine speed
drops.
4.6
Operating tips
Always check that there is the correct volume of
oil in the engine. This is particularly important
when operating on slopes. See 4.2.
Be careful when driving on slopes. No
sudden starting or stopping when driving up or down a slope. Never drive
across a slope. Move from the top down
or from the bottom to the top.
The machine may not be driven on
slopes greater than 10º in any direction.
4.7
Stop
Disengage the power take-off. Apply the parking
brake.
Allow the engine to idle 1-2 mins. Stop the engine
by turning off the ignition key.
Shut off the petrol cock. This is particularly important if the machine is to be transported on a trailer
for example.
If the machine is left unattended, remove the spark plug cable(s) and remove the ignition key.
The engine may be very warm immediately after it is shut off. Do not touch the
silencer, cylinder or cooling fins. This
can cause burn injuries.
4.8
Cleaning
To reduce the risk of fire, keep the engine, silencer, battery and fuel tank free
from grass, leaves and oil.
To reduce the risk of fire, regularly
check the machine for oil and/or fuel
leakage.
Clean the machine after each use. The following
instructions apply for cleaning:
• When washing the machine with water under
high pressure, do not point the jet directly at
axle seals, electrical components or hydraulic
valves.
• Do not spray water directly at the engine.
• Clean the engine with a brush and/or compressed air.
• Clean the engine’s cooling air intake (9-11:W).
• Only Pro25: Clean the oil cooler (12:X).

Battery
If acid comes into contact with the eyes
or skin, this can cause serious injuries.
If any part of the body has come into
contact with acid, rinse immediately
with copious amounts of water and seek
medical assistance as soon as possible.
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery fluid does not need to
and cannot be checked or topped up. The only
maintenance that is required is charging, for example after extended storage.
The battery must be fully charged before being used for the first time. The
battery must always be stored fully
charged. If the battery is stored while
discharged, serious damage will occur.
5.9.1 Charging with the engine
The battery can be charged using the engine’s generator as follows:
1. Install the battery in the machine as shown below.
2. Place the machine outdoors or install an extraction device for the exhaust fumes.
3. Start the engine according to the instructions in
the user guide.
4. Allow the engine to run continuously for 45
minutes.
5. Stop the engine. The battery will now be fully
charged.
5.9.2 Charging using battery charger
When charging using a battery charger, a battery
charger with constant voltage must be used.
Contact your dealer to purchase a battery charger
with constant voltage.
The battery can be damaged if a standard type
battery charger is used.
5.9.3 Removal/Installation
The battery is placed under the tank. To access the
battery, first dismantle the fuel tank as follows:
1. Open the engine casing.
2. Close the fuel cock, see 14.
3. Unscrew the two wing nuts (16:B) and remove
the clamps.
